Talking about wearing glasses and fogging in winter

In the cold winter, the glasses exposed to the air for a long time have a low temperature. When we meet the warm and humid gas exhaled by the nose, condensed water will appear on the surface of the lens, thus blurring our vision.

Therefore, first of all, we can find ways to prevent the mask from "leaking". The feasible operations are as follows:

Normal version: After wearing the mask, press the iron bars on the mask along both sides of the nose to make the mask as close as possible to the face without leaving gaps.

Enhanced version: You can take a piece of paper towel and fold it into a long strip (as shown below) and put it on the bridge of the nose of the mask to fill the gap between the mask and the face, and also prevent the exhaled gas from reaching the lens.

Lazy version: You can also buy a mask with a breathing valve, which can also reduce the possibility of "air leakage" of the mask.

Operation 2: semi-dry soap coated lens!

Maybe even if the mask is worn properly, the glasses will still be foggy if they are not "obedient". It's time to "start" the camera.

You can wipe the lens with a piece of semi-dry soap, and then gently apply it evenly with a clean eyeglass cloth, so that the effect can last for 2-3 hours at a time.

Operation 3: Buy an anti-fog spray for glasses.

If you feel that the above methods are troublesome to operate or the effect is not lasting enough, you can choose to buy special anti-fog spray for glasses.

Generally, the price of anti-fog spray on the market is different, the lasting effect is different, and it is also very convenient to operate.

Operation 4: Buy anti-fog lenses.

If you need to wear glasses all the year round, you can also buy lenses with anti-fog characteristics, which is convenient and fast.

If you are really lazy and feel fed up with the foggy days of glasses, adults can choose to have myopia surgery and get rid of glasses forever as long as they meet the conditions; Children and adolescents can consider wearing OK glasses, and they can prevent myopia without glasses during the day.
